I don't think they make any of these faster larger panels. They do rebrand all of their previous panels they've used in AOC and Philips from Samsung, AUO, etc. They make monitors and change external parts. They like to change backlights etc. then rename the panel. DVR01 is AUO's name for their panel.
Z321QU has the "same" curved panel but offers rip off sync. Can't say it's a popular model either.
Samsung VAs dims pixel parts the other way compared to AUO, that's an easy way to tell them apart. This was always supposed to be AUO, it took similar ages for it to get to market too, the Samsungs have been around for ages, I've yet to see a BenQ monitor with Samsung panel, they probably only use AUO for such panels instead of Samsung.
